Filling in eic

[waynelester]

Hi ,im in the process of completing an eic but have a couple of queries regarding two boxes.the first is "reference method" i assume this is the method of installation ie "c","101","a",etc.but i have also seen other methods ie,"method 1(m1),"method 3(m3).which should be used?. Also there is a box "type of wiring" im not sure what to put? Any advice greatly appreciated

At the bottom of the EIC will be a legend for the tpye of wire uses ie A for T+E that goes in the type of wire

The reference method is out the BRB Appendix 4 table 4A2

All the reference methods are in BS 7671, page 261 onwards.

As for type of wiring depending on which certs you use (NIC) ones have a code along the bottom or side of the page for type of cable. "A" for instance is PVC,PVC cables, "B" is PVC cables in metallic conduit etc.

i must admit to some confusion here. type of wiring no prob, A for pvc/pvc ( T/E ). reference method as previous posts, in BRB given as A,B,C, etc. But having seen previous test sheets, filled in by NICEIC Contractors, reference method has been filled in as "1".

It does make you think doesn't it. You could not even forgive them if they meant I as the method's stop at G. I'm really glad I'm coming to an end of this game that just starting out in it.

I believe some chaps are using the "installation method" number instead of the reference method number.

In BS 7671 There are 73 installation methods (1-73), & 5 for flat T&E 100, 101, 102 etc. Each of these installation methods is also given a reference method (the letters) which is what should be used as it concerns CCC of the particular cable.

I'm pretty sure method '1' was the 16th edition method number for 'clipped direct'

 

[telectrix]

ah, light at end of tunnel. now, how do you ref. cable which is part clipped direct, part buried in wall, part in trunking etc, etc.,

 

[Baal]

Well I always record the worst case scenario

logical captain. spock out

Have a look on page 31 of the electricians guide to the building regs Table 3.3.1
C clipped direct , B Enclosed in conduit on a wall ,100 in contact with plaster board or joist covered with insulation not exceeding 100 mm , 102 in stud wall with insulation touching plaster board , A in conduit in an insulated wall ,101 as 100 but exceeding 100 mm of insulation ,103 surounded with insulation including in a stud wall

hope this helps this table also give the current carrying capacities for the installation method some of which are scary
